java jackson：从 url rest web 服务调用 pojo（带有内部 pojo）作为 json 并将它们映射回 pojo

Question

我用的是jackson，场景是：

在客户端 (Android) 中生成 url 对 Web 服务的调用
Web 服务 return "complex pojo"（与其他 pojo 一样有 class 个成员）作为 json
返回客户端将 json 映射到 pojo

我不知道如何完成此代码以使事情正常进行，尽管我进行了全面搜索并找出了以下起点，但后来我完全堆积起来，我需要帮助...

"complex pojo":

public class MyPojo {
    private List<MyOtherPojo> myOtherPojo;
    private List<HashMap<String, String>> listOfMaps;
    private Map<String, String> map;
    //Constructors, getters & setters
}

客户端代码：

String wsURI = "server.com/myservice?param1=a&param2=b";
try {
    URL url = new URL(wsURI);
    URLConnection connection = url.openConnection();
    BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    StringBuilder sbuilder = new StringBuilder();
    String aux = "";
    while ( (aux = in.readLine()) != null) {
        sbuilder.append(aux);
    }
    ObjectMapper mapper = new ObjectMapper();
    //TODO get myPojo object from his representation as string at sbuilder.toString(); 
    myPojo = ???;
} catch (Exception e) {}

感谢@peeskillet 的解决方案：

MyPojo myPojo = mapper.readValue(connection.getInputStream(), MyPojo.class);
